Importance of Sealing and Protecting Natural Stone

Natural stone materials, such as granite and marble, are popular choices for kitchen countertops and bathroom vanities. Due to the porous nature of natural stone, a sealer needs to be applied at least every five years to prevent water, oil, and other liquids from penetrating into the stone and staining it.

Use a stone cleaner and protector to keep your countertops looking like new between sealing. Watch this video to find out more.

Natural stone is popular because of its character and beauty. But left untreated, water, oils, and other liquids can easily penetrate it, leaving unwanted stains. That’s why it’s important to use a sealer on granite, marble or other natural stone surfaces. A good one will repel spills without changing the color of the stone and should last about five years.

After sealing, use a two-in-one cleaner and protector for daily use, so you can wipe away messes, and reinforce the protective seal on your natural stone surface. This tip brought to you by DuPont Stone Care.


  1. I hired a person to build front porch with brick, last year resealed the brick and replaced some. Can rock salt for snow melting cause the brick to crumble and look like sand.
    Please advise, thank you

    • Hi, Lori,

      Danny says, “We have had great luck using a steamer to clean the grout. It not only cleans it but certainly sanitizes it well. And I would recommend using a grout sealer from Custom Building Products that is available at The Home Depot.”

      Good luck!
